Pre-Filtration System
PVC housing. 5-micron cartridge type sediment filter reduces suspended solids in the feed water stream to RO system. It protects the RO high-pressure pump and RO membrane elements fromclogging up by suspended matters in the feed water. 100 gpm rating. 1No.
Membrane Housing
- The membrane housings are made of fiberglass.
- 8" housing holds 5 membranes.
- 300psi rated pressure vessel, 3 No.
MembranesOnly the best membranes in the desalination industry are used in ForeverPure® reverse osmosis systems.

High pressure side piping material
High grade material and high pressure rating piping is used in ForeverPure® reverse osmosis systems. This ensures extremely safe operation of all ForeverPure® reverse osmosis systems.
- Type of piping: schedule 80 PVC or 316 S.S.
Low pressure side piping material
High grade material is used in ForeverPure® reverse osmosis systems. This ensures trouble free operation of all ForeverPure® reverse osmosis systems.
- Type of piping: schedule 80 PVC or re-enforced high pressure PVC flexible tubing. 150psi rating.
Concentrate control valveConcentrate Control Valve is used to control the recovery rate and operation pressure of RO system.
- Make of Material: 316 stainless steel
Water Quality Monitor
Water Quality Monitors provide instantaneous, real time water quality data. Such data allows the user to determine whether the feed water quality or product water quality is within the original designed parameter. This ensure proper operation and application of the RO system, as well as, the quality of the product water.
Water Quality Monitor Type: digital panel mount
- Feed water TDS Meter
- Product water TDS meter
Flow meters
Flow meters provide feed water, product water, and concentrate water flow rate data to the user.
Flow Meter Type: Panel Mount Flow Meters
- Feed Water Flow Meter
- Product Water Flow Meter
- Concentrate Water Flow Meter feed water
Pressure Gauges
Pressure gauges provide important operation pressure data to the user. They can provide indication on whether the feed water is sufficient, working pressure is proper, or membranes are scaled.
Pressure Gauge Type: liquid filled
Material: 316 SS
- Feed Water Pressure
- Working pressure
- Concentrate
System controls - PLC Based
PLC – Programmable Logic Controller is the brain of the RO system. It allows automatic operation of the RO system, and provides important trouble shooting data through LED lights or HMI interface. ForeverPure® reverse osmosis systems use only the highest quality and most reliable supplier.
Pre-Treatment Systems:
Feed Water Booster Pump (to be determined, not included in the price)
Delivers feed water to RO plant at 40~50 psi at required feed water flow rate.
- Make: Grundfos or equivalent
- Material: 316 stainless steel.
Acid Dosing System (LMI Brand-USA)
The most effective way to prevent calcium carbonate scale formation is to lower the feed water pH via the injection of an acid. The acid will convert bicarbonate ion into carbon dioxide.
One metering injection systems will be supplied for controlling different elements in the feed water of the RO plant. The metering pump will allow controlling of different functions such as the stroke length and percentage rate. The Chemical Dosing System prevents membrane from scaling.
Antiscalant Dosing System (LMI Brand-USA)
One metering injection systems is supplied to inject antiscalant into the feed water stream. The metering pump pumping rate can be adjusted by varying the stroke length and percentage rate. The Antiscalant Dosing System prevents the membrane from scaling.
Multi-Media Filter
Multimedia filter is designed to make better use if the bed depth in the removal of a greater volume of suspended solids. This is achieved by loading larger media granules of lower density at the top of the bed, with at least one layer of smaller media granules of higher density below it. The larger granules remove the larger suspended particles, leaving the smaller particles to be filtered by the finer media.
Depth multi-media filtration system is used to filter sand and sediment (turbidity) down to approximately 20 Microns. Automatically backwashes when filter is clogged. Saves replacement filter cost. Corrosion resistant, high performance composite & fiberglass tank will be used to hold the media. 42" x 72", 1. No.
Post-Treatment Systems:
pH adjustment System (LMI Brand-USA)
One metering injection system is supplied for the controlling of pH level of the product water. The metering pump pumping rate can be adjusted by varying the stroke length and percentage rate. The pH adjustment system adjusts product water pH by injecting caustics into the product water to raise product water pH.
Membrane Cleaning and Flushing Systems:
Permeate Water Flush
The Permeate Water Flush function purges the salt water out of the system by pumping permeate water into the membrane housing before each shut down and before every startup. By having permeate water during the shut down period, high salinity water would not permeate into the product water side. This maintains product water quality and extends the membrane life time.
Built-In Membrane Cleaning System
It includes a 316 SS high flow pump. It cleans the membranes and can be used to sanitize the membrane system. The user can initiate the cleaning process on the control panel. Cleaning should be done periodically or should be done when the Delta P between the lead end of the membranes and the tail end of the membranes is above 30 psi. The sanitization function is especially useful if the RO is used for bottled water or beverage production.
Miscellaneous Items:
High Product Water TDS Diversion With Alarm
If the product water TDS rises above a preset value, then the system will trigger an alarm and divert the unqualified product water into the drain. This function ensures only product water that is within the present TDS range is delivered to the user.
